Should I clean my deck before sealing it?

Y ou should clean your deck before sealing it. Cleaning before refinishing is critical. If you don’t remove dirt and debris, you'll trap moisture in the wood, which prevents the new sealer from working correctly and can lead to costly repairs. Whether you need to sand, power wash, or sandblast depends on your deck's condition.

Is it better to seal or stain a deck?

Sealing and staining your deck are essential maintenance methods that protect and beautify your outdoor space. Stain adds rich color and guards against fading, while sealant fortifies the wood against moisture and weather damage. Wood type, climate, deck age, and the degree of existing damage determine whether your deck benefits from one or both treatments. Using both options extends your deck’s durability and enhances its overall appearance.

How much does it cost to power wash and seal a deck?

Power washing and sealing your deck costs $500 to $1,700. This process combines the removal of stubborn dirt and debris with a protective seal that preserves the wood’s integrity. Effective cleaning eliminates harmful buildup, and a proper seal prevents moisture damage and wood decay, ensuring long-term durability and reducing future repair expenses.

How often do decks need to be sealed?

Your deck must be sealed every one to three years to maintain its strength and appearance. Regular sealing is essential to protect the wood against moisture, mold, and harmful UV rays. A consistent sealing schedule prevents rapid deterioration and costly repairs. Inspections should be performed annually to determine if the protective layer remains intact, extending the life of your deck.

Can I leave my deck untreated?

Leaving your deck untreated compromises its structural integrity and safety. An unprotected deck rots quickly due to moisture and environmental exposure, which means that neglecting sealing results in rapid decay and expensive replacement costs of $4,125 to $11,650. Sealing your deck is essential for maintaining its durability and protecting your home.

How long does it take for the sealant to dry, and when is it safe to use the deck?

The sealant on your deck dries within a few hours and reaches full cure within 72 hours before regular use. It is essential to wait until the complete curing period to ensure the protective layer fully sets and resists weather and foot traffic. Proper drying guarantees that your deck is fully protected against moisture and environmental damage, ensuring lasting quality.

"Thomas M was an excellent technician and did great work fixing all the basement windows around the house. These windows are difficult to find a replacement but he was able to repair and repaint them. The other technician was Pablo He worked on caulking all the windows around the house and he did some filling work on the garage sliding doors You did a good job, but Pablo left his trash around and didn’t pick up after himself so Thomas M and I did that on the third day. It took three days total, but it was two men for two days and one man for a 3/4 of a day actually. Although I’ll probably get charged for a full day, since it went past noon. The labor portion is the most expensive and a little higher than I initially anticipated. So, I was hoping for a quicker turnaround, but overall quality work was completed. I would highly recommend Thomas M as a technician to do future work. He’s very knowledgeable, friendly and does a great job. I would hire again but include more details in the contract language."
